摘要

The synthesis of E-alkenylstannanes from aldehydes and a mixture of Bu3SnCHBr2, LiI and CrCl2 is described. A mechanism is proposed to account for the alkene geometry in chromium (II)-mediated alkene synthesis which involves stereoselective addition by a gem- dichromium reagent to an aldehyde followed by a stereospecific elimination step.
